VALVE MECHANISM.

Specification of Letters Patent.

Patented Feb. 27, 1912.

Application flied April 28, 1907. Serial No. 369,744.

To all whom it may concern:

Be it known that I, PEIRCE D. Sommcx, a

citizen of the United States, residing at Dayton, vin the county ofMontgomery and State of Ohio, have invented certain new and usefulImprovements in Valve Mechanisms, of which the following is aspecification.

My invention relates to valve mechanisms and particularly to theapplication of controlling means for the air inlet as used on thecarburetof a motor car, and the invention ha: its objects; the provisionof valve controlling means whereby the motor may be more readilystarted, especially in cold weather; to provide a control for the. airinlet which may be easily operated from the exterior of the motorcasing; to rovide. a convenient means for temporarily ioldmg the airinlet closed; and to provide a means for holding the air inlet closedwhich will be automatically opened by the vibration due to the startingof the car. One embodiment of my invention is shown in the accompanyingdrawings in which-.

F1 ure l is a side elevation of the front part the motor car, the motorcasing being broken away to dlsclose the controlling means for the airinlet valve to which my invention particularly relates,

Figure 2 is a detail section showing the valve for the air inlet. andthe means for controlling the valve, and

'Figure 3 is a plan view of the device as shown in Figure 2.

it has been found that it. is also diilicult to start. a motor car,especially on cold days, because of the admission of an excess of coldair to the carburetor which excess of cold air retards the operation ofthe carburetor and the ready starting of the motor. venlion is designedto overcome this dilliculty by the provision of means for temporarilyclosing the air inlet valve .at. the time the motor is started, therebeing sullicicnt air in the pipe 4 andthe carburetor to provide the airrequisite for the first few explosions before the valve is opened.Furthermore, as this closure is desirable only at the time of starting,myinvention is designed to provide automatically for the releasing ofthe means for holding the valve closed when the vehicle is started. Inthe embodiment of the invention as herein shown and described, this isaccomplished by making the valve spring closed, :and pro vidin a catchwhich is in position to be jarre open by the vibration of the. car.

Referring now to thedrawings, 1 is the body of the car which may be ofany approved form, 2 is the casing which as shown in Figure 1 is brokenaway to clearly disclose the interior part, 3. is the carbureter, 4 y

is the air inlet pipe for the supply of air to the carbureter, 5' is thecontrolling valve therefor held normally in open position, by means ofthe spring 6, 7 is the operating rod for the valve which rod looselyengages the valve 5, and 8 is a bracketthrough which the rod 7 passesand which is ada ted to cooperate with the projection 9 on t e rod for.

holding valve 5 shut (see Figure 2). The pipe 10 serves to conduct themixture of gas and air from the carbureter to the motor. It will benoted from Figures 2 and 3 that the valve 6 is of the gate pattern andis adapted to be fully opened or entirely closed, the spring 6 normallytending to hold the valve in full open position. The rod Textends to theexterior of the casing for convenience of operation, and is as shownprovided with a knob. This rod 7 is loosely connected to the end of thevalve 6 so that such rod is capable of a slight vertical motion by whichmotion the catch 9 is released from the bracket 8, when desired. As itis.

desirable to retain the valve in closed posin91 Shown in Fig. 2, onlywhen the car is l-l lllllg, the catch 9 is provided on the upper side ofthe rod 7 so that the jarring of the vehicle in motion will disengagesuch catch it the rod is inadvertently left in the position of Figure 2after the motor has started. The closing of the air inlet when the:motor is started serves to accelerate the action of the carburetor andmotor by excluding' the-cold air and at the same time increasing the pmportionof combustible in the explosive mixture. the foregoing that thecontrolling valve is easily operated and that if desired no. atten-'tion need be paid to this valve after it is placed in the position shownin Figure 2,

as the catch will be automatically released by the vibration of themotor or the vehicle after the parts'are in operation.

Having thus described my invention and illustrated its. use, what Iclaim as new and desire to secure by Letters Patent, is the following:

1. The combination with a carbureter, of a valve for controlling the airinlet, yield- It will be seen froming means for holding the valve open,means for closing the 'valve and retaining means cooperati with suchlast'means for holding the va ve shut-against the tendency of theyielding means to open such valve, and

adapted-to be disengaged by the vibration incident to the operation ofthe motor with which the carbureter is used so that the valve may open.

2. The combination with a carbureter, of

an air inlet for the carbureter, a valve for such that the parts willbeautomatically disengaged by the vibration incident to the operation ofthe motor with which the carhureter is .used to permit the yieldingmeans to open the valve.

3 The combination" with a oarbureter, of an air inlet for thecarbureter, a valve there for, yielding means for holding the valveopen, and a rod for closing the valve provided with a catch adapted tobe disengaged by the'vibration incident to the operatlon of the motorwith'whieh the carbureter isnsed for temporarily holding the valveclosed.

In testimonywhereof I have hereunto signed my name in the presence ofthe two subscribed Witnesses.
